WILLIAM J. MINGLE, OF LANCASTER, PENNSYLVANIA.

WATER-MOTOR.

SPECIFICATION forming part of Letters Patent No. 357,220, dated February 8, 1887. Application filed March 30, 1886. Serial No. 197,210. (No model.)

.To all whom, it may conoerm Be it known that 1, WILLIAM J. MINGLE, of Lancaster city, county of Lancaster, and State of Pennsylvania, have invented certain new and useful Improvements in Water-Motors, of which the following is a description sufficiently full, clear, and exact to enable.

those skilled in the art or science to which these improvements appertain to make and use the same- Thisinvention relates to water-motors which are provided with buckets having curved faces to receive the impact of the water, and with spray-deflectors for preventing retardation of the wheel by the action of spray.

Said invention consists in the peculiar construction of buckets having on their faces two curves arranged to'receive the full force of the jet at two points directly before each bucket passes out of reach of the water-jet.

The said invention also consists in the combination, with a wheel having a series of buckets, of a series of curved exterior spray-deflectors, each provided with a plate which extends from the back of said deflector, diverge ing gradually from said wheel, so that the spray will follow the line of said plate to the next deflector of the series and be converted into a stream bysaid plate and said deflector and directed to the discharge-pipe.

The said invention further consists in the combination of a Z-shaped recessed guard for preventing the escape of water with a spring for forcing said guard against the shaft-spindle of the motor, and a chamber and passageway which conduct the water stripped from the journal in this manner back to the interior of the motor-casing.

The said invention also consists in'the peculiar construction of the bottoms and side outlets of the buckets, and in other improvements in construction, and combination, hereinafter more particularly set forth.

In the accompanying drawings, Figure 1 represents a vertical section of my improved water-motor, taken at right angles to the shaft or spindle thereof. I Fig. 2 represents a vertical section on the line 00 m, Fig. 1. Fig. 3 represents a perspective view of one of the buckets and a part of the periphery of the wheel on which it is formed. Fig. 4. represents a vertical section through the same, looking away from the face which receives the impact of the water. Figs. 5 and Grepresent sectional views taken through a partof the wheel at right angles to the shaft, showing the impact of the water on thefirst andsecond'eurves, respectively. Fig. 7 represents in detail a section through the spindle and an end elevation of the leakage-guard and the spring bearing against the latter.

wheel mounted. on and turning with said shaft,

and E E the nozzles whereby jets of water are directed against 'the buckets of said wheel. Water passes to said nozzles from a source of supply outside of casingA through a pipe, F,

which may be provided with a strainer, G, and.

an extension, H,of said pipe. This extension H, as shown in Fig. 1, is attached by screwthreads, and therefore removable. The nozzles E E, already referred to, are formed in its sides. In this extensionis a cylindrical valve, 1, provided with a handle, J, extending outside of the casing A, said valve having on opposite sides of it two openings correspond ing to'those in extension H and to said nozzles. By means of this device I am enabled to out off one or the other of said nozzles, and thus make'use of a jet of greater or less volume at will. r

The wheel is provided, as usual, with radial .spokes d, and with buckets K, arranged conder that the water injected into said bucket may escape simultaneously at bothsides thereof through said openings Z in an obliquely downward and lateral direction. The face of the bucket which receives the impact of the water-jet is provided with two distinct curves, at m, arranged in the same vertical plane transverse to the axis of the wheel. These curves vary in curvature,theinnercurve, m, being for a circle of much greater radius than the outer curve, at, and the position of the former being forward in the direction of rotation, whereas the are of the latter is nearly radial. The jet of water first strikes the curve m in the center. The wheel continuing to revolve, the curve 121/ is then presented, so as to be struck in the center likewise. This obviously would not be possible if both curves had the same curvature and inclination, since the bucket-blade changes its inclination with respect to the water-jet as the wheel turns. Nor would it be possible to strike both buckets centrally if they were not in the same vertical plane transverse to the axis of the wheel,since the jet, of course, never leaves that plane. During the interval between these direct impacts on the center of said curves the jet, of course, acts less directly on the intervening parts thereof; but this doubly-curved construction insures two direct applications of the jet to the center of a curvature on a face of each bucket during the passage of said face across the line of action of said water-jet.

Deflectors O 0 O rigid with the inside of easing A, present curved faces opposite to the direction of rotation of wheel D. The first of these, 0, as shown in Fig. 2, has lateral extensionso, which nearly close the spaces at the sides of the buckets, and prevent the spray and water which pass through openings Z from passing beyond said deflector between the wheel and the casing. This deflector has a rearwardly-extending guide-plate, I, which gradually diverges from the curvature of the wheel, and guides along it the spray which flies off from the outer parts of the buckets as they revolve. This guide-plate P tern1inates before reaching the curved face of deflector O, and the water which has followed said guide-plate passes thence against said deflector, and is turned back into the space along the inner face of the casing, which it follows downward until it joins the water turned by the first deflector, O, and thence into the discharge-pipe Q.

The second deflector, O, as shown in Fig. 2, may be provided with lateral wings 0, like the wings 0, already described, and has a diverging rearwardly-extending guide-plate, P. Its operation is in all respects the same as that of the first deflector, O, and the first guideplate, P, already described, acting on whatsoever spray passes these latter devices.

The third deflector, O and its guide-plate P are located beyond deflector O and guideplate P, and substantially repeat their action, except that the force of gravity alone is relied on for the return of the liquid which passes beyond guide-plate P and, therefore, to effect more complete concentration of the spray into flowing water, the guide-plate I is not deflectcd from the periphery of the wheel, but follows the latter almost exactly. These deflectors O O O" are arranged opposite the solid outer parts of the sides of the buckets, but not opposite the openings Z. Consequently the water from said openings will not strike said deflectors, and thus the obstruction of the wheel thereby will be avoided.

By my guide-plates and deflectors the spray flying from the periphery of the wheel is gradually condensed into flowing water, which will not be supported by the air nor dashed back against the buckets, but turned harmlessly down into the outlet. Plates arranged across the path of trajection would not answer, because they would necessarily increase the spray instead of diminishing it; but the gradual action of my plates allows nothing of the sort, and effects the purpose stated most satisfactorily.

Although three deflectors have been shown and described, I do not limit myself to any particular number. There may be but two, or there may be more than three, their action being cumulative.

It designates the belt-wheel whereby the shaft or spindle G is driven, S the lubricator applied thereto, and T a chamber formed in an offset of easing A to receive all water and oil which may follow said spindle or shaft toward the end of the latter. From this chamber a passage, t, conducts said liquids to the interior of the casing. To strip such water or oil from said spindle or shaft and direct it into said chamber, I employ a leakage-guard, Z, which has the shape of that letter in plan view. Its top is recessed at the ends, and also the intermediate oblique portion, to fit the under side of said spindle. Aspring, WV, bears against the under sideof this leakage-guard and holds it against shaft 0.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a water-motor, a wheel having a series of peripheral buckets, each of which is pro- ICO vided with two curves, m and m, arranged in the same vertical plane transverse to the axis of the wheel, one of said curves being outside of the other, and their curvature and inclination varying in order that each may receive a distinct central stroke of the water-jet, substantially as set forth.

2. A motor-wheel provided with a series of buckets having openings Z-through the inner parts of their sides, in combination with a series of deflectors arranged in proximity solely to the solid outer parts of said sides, in order that the water escaping through said openings may not strike them and retard the wheel, substantially as set forth.

3. The Z-shaped leakage-guard Z, in combination with a spindle or shaft which it is re cessed to fit, and a spring which bears against said guard, substantiallyas set forth.
